java.lang.Object com.ibm.icu.text.CanonicalIterator
public final class CanonicalIterator
This class allows one to iterate through all the strings that are canonically equivalent to a given string. For example, here are some sample results: Results for: {A WITH RING ABOVE}{d}{DOT ABOVE}{CEDILLA}
1: {A}{RING ABOVE}{d}{DOT ABOVE}{CEDILLA} 2: {A}{RING ABOVE}{d}{CEDILLA}{DOT ABOVE} 3: {A}{RING ABOVE}{d WITH DOT ABOVE}{CEDILLA} 4: {A}{RING ABOVE}{d WITH CEDILLA}{DOT ABOVE} 5: {A WITH RING ABOVE}{d}{DOT ABOVE}{CEDILLA} 6: {A WITH RING ABOVE}{d}{CEDILLA}{DOT ABOVE} 7: {A WITH RING ABOVE}{d WITH DOT ABOVE}{CEDILLA} 8: {A WITH RING ABOVE}{d WITH CEDILLA}{DOT ABOVE} 9: {ANGSTROM SIGN}{d}{DOT ABOVE}{CEDILLA} 10: {ANGSTROM SIGN}{d}{CEDILLA}{DOT ABOVE} 11: {ANGSTROM SIGN}{d WITH DOT ABOVE}{CEDILLA} 12: {ANGSTROM SIGN}{d WITH CEDILLA}{DOT ABOVE}

String |
getSource()
Gets the NFD form of the current source we are iterating over. |
String |
next()
Get the next canonically equivalent string. |
